oil

[nsmitchell]

I only use REAL OIL! None of that "synthetic voodoo snake oil".

[Spades]

meh, I am a broke little bastige, so I use Valvoline Synthetic Blend 5w30, and STP filters.

Royal Purple,Mobile 1,Amsoil, and others are much better, but they also cost double or more per quart than the valvoline does.

After some research, I had decided on the last 3 cars I have owned to use semi-synthetic, as there are pro's and cons to using full sythetic or just regular oil. So, after much debating I settled on a blend.

EDIT: on the thread jacking question of octane, all octane rating really does is determine at what point predetionation occurs. If you are running a engine with high compression or forced induction high octane fuel is a good idea, but on a gas miser car that was designed to run on pisswater gas, you won't notice any performance differance.

[Spades]

Yeah, mobil 1 filters rock(can't afford them since I change my oil every 1,500-2,500 miles).

[/Threadjack]

As far as rev'ing higher...how high do you need? I mean, jeebus, I power shift at 6300RPM's to get a nice 1 to 2 chirp...seriously...why would you want it to have a higher redline? 6k+ for hp range is plenty high enough...

The cars top speed is governed, so it wouldn't go any faster. I could care less if the car made its peak power and you shifted at 3k RPM's as long as I had enough gearing to go 100mph(for the occasional 1/4 mile run,if the car was actually faster),lol.

Now, more low end torque, that is what the car really needs!

More low-end would be good too, of course. As far as redline goes, higher revs usually equal higher hp numbers on top. I'm just dreaming of one more thing that would make a nice hi-po Yaris motor: turrrbo, pretttty forrrged things, lightened things, head-job, fuel management... etc., etc. Higher revs are always fun but not always practical.

Higher RPM's do not more HP numbers make...just because riceboy in his built b18 integra makes his peak HP at 9k RPM's does not mean a yaris will.

In the performance section a turbo kit for the yaris is being tested as we speak...and if I remember correctly they are around 180hp without building the bottom end to make the engine rev higher. High RPM's mean more to go wrong...rods through the block are a example that comes to mind.

It will be very hard to use a stand alone engine management system to control the motor at high RPM's, because the yaris' throttlebody is electronic...much more difficult to get a EMU that will work with it.

Fuel modifications, bigger valves & cams, and boost however, these are things we both agree on!

Anyone wish to start the time honored debate of Synthetic VS Synthetic Blend?

I'll avoid the oil debate but still disagree on the RPMs. 9000rpms is nothing for a 1.5L engine, if built properly. A 1.5L should be able to do 12k with no issues. But why spend the money. Engine management is a huge issue, of course. 180hp on a stock bottom with a 6500 rpm redline does make all the fuss of getting into anything else seem almost pointless.

and for that matter....... Synthetic oil rocks!!!

I couldn't help myself.

It has been proven for years, all over the web, that small 4 banger car and motorcycle engines actually produce LESS POWER with higher octane gas. It is a myth to think that our Yaris engines benefit from higher octane gas, no such thing as "imrpoved MPG" either. Our Yaris engines are not even chipped for higher then 87, and are tuned to run optimally at 87. But try telling this to the boy-racers that equate dicking with their engines and changing the oil monthly with masterbation.

Burning gas higher then Octane 87 is just wasting money, and makes your engine produce LESS POWER...hello?!? Octane slows down the combustion of the gas....leave it for bigger higher compression engines that need that retardation, that are tuned by the factory for higher octane gas. Why would you force the combustion to happen too late in the cycle?!? Incomplete combustion means more stress on the motor, less longevity, and provides a false sense of being. Perhaps you know more then Toyota engineers?

Through my kids, I know many Ricer-Boy teenagers that always fill up their Civics, Integras, Corollas etc with Octane 89 or more...what a waste of money! They have this dillusion of "more power"! Dillusions and superstition are hard to overcome, sadly...

I tried to explain why there is octane ratings, but, people don't want to listen. As Pavel said, causing the Fuel to burn later that it is supposed to is not such a good idea. When you get boosted, then go for octane, untill then, all it does is mess with a good design. Remember kiddies, just because the guy down the block puts high octane fuel in his stock 89 civic doesn't mean you should too.

P.S. Sport Compact Car had a whole issue devoted to urban myths about ricer "power" legends. High octane was one of them...and no, you do not get more HP out of higher octane fuel...and also, the octane boosters you buy at walmart actually cause more build up of crap in your fuel system, and most of them don't even boost the octane. Please...stop trying to make a stock compact gas miser car into something its not unless you f--k with the compression or add boost to the equation.

So true Spades....and besides, we all know that if one really wants to add pazzazz to a cars performance, just add a thimble fill of diesel to the....

High octane fuel in a Yaris engine makes it retarded!

There! It needed to be said!

Here is an interesting article I found that might interest people on this gas dispute.

Boy that guy likes to write!!!! The last 2 paragrahs sum it up though.

THE LAST 2 PARAGRAHS ARE:
"On modern engines with sophisticated engine management systems, the engine can operate efficiently on fuels of a wider range of octane ratings, but there remains an optimum octane for the engine under specific driving conditions."

"If you are already using a fuel with an octane rating slightly below the optimum, then using a higher octane fuel will cause the engine management system to move to the optimum settings, possibly resulting in both increased power and improved fuel economy."


I'm about the oldest codger on this site, and these 2 paragraphs say it all. On pre-engine management engines 8 or 9 pounds of compression ratio would run efficiently on regular (87 octane), any more compression and you would have serious knocking if going up hill or accelerating faster than a snail. (unless you retarded the timing to the point the engine would barely run) 87 octane is not the optimum for 10.5 to 1 compression ratio without engine management. It does fine with regular when driven like the hypers do (little or no load), but under acceleration or going up hill, timing retards (out of the optimum setting) to prevent knock. From his last 2 paragraphs, he basically agrees that premium would help performance and milage during load conditions. Soooo---Hypers don't need it....normal drivers may benefit, depending on the environment and how heavy their foot is!

tsb report of 5w-20 oil

[mandriu]

I don't know much, but i do know that the first number in 5w-20 indicates that the in the winter(around freezing) the cold oil would have a lower pour rate than the 0w-20. thereby decreasing lubrication until the engine has reached a warmer temp. In these summer months the 20 of either of the oils would take precedence. Unless you live on the north pole. The actual synthetic oils do not have a state changing property(in normal temps 0C-100C) like mineral oils.

Apparently Pennzoil has found a full synthetic which changes. I use it in my old Probe without any issues..

[nsmitchell]

Pennzoil, Quaker State, Valvoline... They all send shivers up my spine! Synthetic or not, these companies are scary. I just don't trust them, kinda like Chrysler, Ford and GM!
